JS Engineering Oy

Fast, professional and friendly service. Highly recommended!

I have to admit, great customer service! The "power software" was removed from the car and replaced with a new one, the fuel consumption dropped significantly and the desire to travel also increased! I would be happy to do business with them in the future! :)

Mercedes-Benz E 350cdi 4matic 2012 went on that laptop. Engine. power, EGR off, DPF off, soft limiter off, AMG menu, Manual mode for gears and traffic sign recognition programming. It came out exactly as I hoped. There are pulls and the amount of smoke is reasonable, so-called power smoke is flat but it doesn't constantly make a terrible snort. It's good that I got that manual mode too, it's much easier to throw a ring with that four-wheel drive automatic when it doesn't start to shift so sensitively, the speed also stays more controlled. And that AMG menu was good because it shows the engine of this age. Oil temperature + coolant temperature and also a big plus because it shows the gear on the instrument cluster. I used to be bothered by these pre-facelifts because it doesn't show how many gears are on as standard on the instrument cluster. And even though he took the soft limiter off, at least it didn't get so bad on a warm engine that it would have been a nuisance. Excellent and fast service. I took the car to the location the night before and it was ready at 2pm the next day. During the programming, there were lots of updates, pictures and videos. And questions, for example, about whether the amount of smoke was good for my taste. And at the end he said that if there were any problems, just bring the car back and we'll take care of the problems.

It was nice to get more kick. The heavy car felt a little lighter.

Good customer service and knowledgeable. Now the car is running well :D
